Hello all,
If you have decided to bite the bullet and want to upgrade your oem speakers I would strongly recommend the MB Quartz upgrade made for Golf Mk5's.
I had to end up changing all my car speakers as a Chinese Android stereo upgrade sent frequencies my speakers couldn't handle. However along with the OEM speakers I ended up selling the deck on and upgrading to a Pioneer double din. Best decision I had made in some time.
Below is a picture of the original setup:-
I was disappointed to find there were no mid speakers from factory! Just vents of some sort.

After:-
Please note the mids slot into the door cards hence you can only see the 8" woofer.

The speakers in question

I had to purchase the speakers directly from Germany however ended up doing through Amazon so wasn't too bad. Overall a very good upgrade however I will only see the true potential once these are coupled to an amplifier.
On a side note have plenty of sound deadening material ready as you will notice extra vibrations from the door cards.
Cost of speakers for £230.
Any questions fire away.
Thanks
